Patent CA-2297347-A1 (CA)
Inventor: YAMADA MASAHARU
IPC: B28B3/00
Filed: 2000-01-27
Abstract: The present invention provides a magnesia-spinel refractory in which corrosion resistance and slag penetration resistance are significantly improved. The magnesia-spinel refractory is obtained by mixing magnesia granulated powder having a particle diameter of 10 to 150 µm and alumina powder having a particle diameter of 0.1 to 5 µm, molding the resultant mixture, and then burning the molded product to form a dense and strong combined structure of periclase and spinel. The mixture of magnesia and alumina contains powders of both components, or a powder of one of the components and a granulated powder of the other component. It is preferable to use a spray dryer method as granulating means, and a hydrostatic pressing method as molding means. These mixtures are used for producing magnesia-spinel protecting tube and crucible, bricks for copper smelting and converting furnaces, and magnesia-spinel protecting tube and crucible for copper smelting and converting furnace slag. In this case, the hydrostatic pressing method is used.

Title: Device for turnable windows
Inventor: OEHMAN HANS
IPC: E06B3/40
Filed: 1998-10-02
Abstract: The invention concerns a device for turnable windows comprising a frame (2) and a casement (1). The frame (2) is formed on each one of two facing side faces with a longitudinal groove (9). The casement (1) is piv-otally mounted on a link-arm mechanism (3, 7) and on two oppositely directed edge side faces said casement (1) is formed with a guide bushing (8a, 8b), said bush-ings travelling in their associated one of said longitudinal grooves (9). By means of a rotatable lever (12) said bushings are arranged to be extended or retracted simul-taneously in pairs out of respectively into said grooves (9). When two of said guide bushings (8a and 8b, respectively) engage in one longitudinal groove (9) each, said casement (1) may be pivoted in the reverse direction over half a turn and be closed in said reversed posi-tion by retraction of the two non-engaged guide bush-ings (8a and 8b, respectively) and renewed extension thereof into renewed engagement in one groove (9) each.  From this closed position said casement (1) may be pivoted in the reverse direction by renewed retraction of the last-mentioned two guide bushings (8a and 8b, respec-tively) out of engagement with said grooves (9) or, alternatively, may continue to be pivoted in the same direction by retraction of the two remaining guide bushings (8a and 8b, respectively) out of engagement with the grooves (9).

Title: Accelerator pedal
Inventor: DJORDJEVIC NEBOJSA
IPC: G05G1/38
Filed: 2000-04-12
Abstract: An accelerator pedal assembly has a mounting bracket and a pedal arm mounted to the bracket for pivotal movement between an idle position and a full throttle position. A biasing mechanism extends between the pedal arm and the bracket for urging the pedal arm to the idle position. A friction disc engages the biasing mechanism for movement therewith. The friction disc is in frictional engagement with a stationary friction plate for relative movement therebetween. Movement of the pedal arm from the idle position towards the full throttle position responsively rotates the friction disc relative to the friction plate and the biasing mechanism responsively increases frictional engagement between the friction disc and the friction plate by urging the friction disc and friction plate together.

Abstract: The Mystery Box is a self locking container, which requires manipulation of its construction components to open it. It consists of as series of moving walls, floor, trim and legs which, if handled in the correct sequence, will reveal a secret compartment containing a "key" which will eventually be used, during the final step of the operation, to open the lid. Following the discovery of the key, the predetermined rotation of its legs will allow the upper section of the enclosure to slide thereby permitting movement of the wall parts. A number of the exterior wall slats may then be moved in a set staged sequence eventually resulting in the revealing of an access outlet. The "key" at this point may be inserted in this aperture and thus release the ultimate internal locking device of the Mystery Box.

Title: Augmented retinal display with view tracking and data positioning
Inventor: JOHNSTON RICHARD S
IPC: G02B27/00
Filed: 1999-01-13
Abstract: A scanned beam tracking system (32) is included in a virtual retinal display (10/50). An infrared light source (34/52) generates light for scanning the viewer's environment in the direction the viewer is looking. A visible light source (52) generates visible light which is scanned on a viewer's retina to generate a virtual image. A common scanning system (26) is used to scan both the non-visible light and the visible light. The visible light is directed into the viewer's eye. The non-visible light is directed away from the viewer's eye into the environment. Infrared reflectors (42) are positioned in the environment (40). When the infrared light from the virtual retinal display scans over a reflector the reflector directs the infrared light back toward the virtual retinal display. The current pixel of the scanning cycle when the infrared return light is detected corresponds to the position of the reflector.

Title: Reduction of the crest factor in ofdm signal
Inventor: FIFIELD ROBERT
IPC: H04L27/26
Filed: 1999-09-29
Abstract: A method of operating a radio communication system uses orthogonal signals for transmission of packets of data between two or more stations. In the transmitter data is encoded (204, 206, 208) onto a plurality of orthogonal carriers by a differential phase modulation technique, for example DQPSK. The carriers are combined into a single signal by an inverse discrete Fourier transform (210) and clipped at a predetermined amplitude (212) before being transmitted (218) to reduce the crest factor of the transmitted signal. The phase of one or more of the carriers is randomised before each data packet, hence a different crest factor will result for retransmissions of the same packet. This ensures that if a packet is difficult to transmit, because of reduced signal to noise ratio caused by clipping, it will retransmit successfully.

IPC: A01M1/20
Filed: 2000-10-26
Abstract: An insect control station for baiting and/or trapping insects that includes a base, a cover, and an insert locked between the base and cover. The insert is preferably a glueboard or tray. The glueboard, to which insects stick, is used for trapping insects in an environment. The tray is used for holding a toxic bait or attractant that the insect takes back to its nest. The tray may also be used to hold glue for trapping purposes. To maximize the safety of the naive person, especially a child, who does not know what an insect control station is, the base and cover are locked to each other with two hand operated keyless locks that operate independently of the other. The keyless locks are recessed relative to the cover at a span having a width greater than a child's hand such that a child may not operate the locks at the same time with one hand. The operating portion of the lock is located on the base so that if two hands operate the two different locks, the cover will not move. Further, the cover must first slide away from the locks before the cover may be removed from the base, whereupon access to the interior is gained. The base and cover are shaped to hold the insert against a floor of the base even if the insect control station is mounted upside down. The insect control station further has a low profile so that it can be tucked into narrow spaces, is rigid so that it can be stepped on without damaging the insert, and includes ramped openings for the crawling insects. The invention further discloses a method for controlling insects.
